Description
本申请要求于2016年8月15日提交中国专利局、申请号为201610671376.4、发明名称为“一种网络切片配置方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信技术领域,尤其涉及一种网络切片配置方法及装置。
未来第五代移动通信网络(the fifth generation,5G)将可以支持更加丰富多样的业务类型与用户需求,包括速度,容量,安全性,可靠性,可用性,时延以及能耗等方面都要实现大幅度的升级。与现有第四代移动通信网络相比,5G网络需要满足更多的需求:网络流量将数以千倍的增长,需要连接的设备数目相比现在增加一百倍以上,而有些业务要求极低的延迟。5G网络将针对未来业务的多样性,提供“网络定制化”的服务,网络架构将更加灵活,运营商将可以对关键性能指标(key performance indicator,KPI),如速率,容量,覆盖,可靠性,时延等进行灵活组合,使得网络架构可以满足各个具体用例的需求。
传统的移动通信系统使用垂直架构,从物理资源到协议支持,用于满足可预测的KPI需求,适用于单一服务型的用户网络,然而,垂直架构很难根据灵活的用户需求进行自适应调整,并满足新型用例的需求,因此,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)在5G网络架构中提出了网络切片(Network slicing)的概念,网络切片为支持特定用例通信业务需求的逻辑网络功能组合。网络切片将使用逻辑资源,而不是物理资源,帮助运营商提供以业务为基础的网络架构,这样的网络服务将提供分配和重新分配资源与需求,允许独立网络功能模块的可扩展性与物理与虚拟化功能的灵活部署,实现网络资源的充分有效利用的同时,满足业务性能的需求。
3GPP关于网络切片的很多技术实现仍在讨论中,目前仅给出了网络切片概念以及潜在的网络切片架构,对于无线接入网(radio access network,RAN)侧,如何感知网络切片的配置过程,还没有一个明确的解决方案。

实现5G网络切片的关键推动因素在于软件定义网络SDN(software defined network,SDN)与网络功能虚拟化(network function virtualization,NFV)。SDN技术颠覆了网元形态,实现网络功能与硬件解耦,从而允许垂直系统被细分为可编程的功能模块,形成可连接的水平网络架构,适用于灵活的扩展服务,并根据业务需求通过可编程功能将网络连接作为服务提供,实现“网络即服务”的目的。移动运营商在核心网(core network,CN)的控制平台上通过一系列网络功能的配置与编排实现成百上千的网络切片的配置与管理。网络切片涉及端到端之间的网元的一系列配置与支持,包含用户设备(user equipment,UE)端、接入网(radio access network,RAN)等设备,除了在CN创建网络切片,在接入网侧,需要核心网以及运维与管理OAM(operation and management,OAM)实体通过对接入网侧网元的配置,来实现对端到端网络切片的业务进行区别化处理,保证对应的服务等级协议(service level agreement,SLA)的要求,从而更好的支持端到端的网络切片。
网络切片将可以实现网络服务质量(Quality of Service,QoS)的隔离,灵活的网络管控与网络效率的提升,网络管理者将可以根据端到端的QoS需求进行分解,映射到不同的子网络系统与转发设备,同时以低成本,高速率的方式为建立网络切片,并不影响现有的业务。切片可以提供部分灵活的可编程接口开放给第三方用户,从而使得第三方用户可以基于开放接口设计并开发信的网络业务并实现快速部署,为运营商带来可观的经济效益,同时提高了现有网络的使用效率。
目前,3GPP(the third generation partnership project,3GPP)对5G的典型场景用例归纳为以下三种:增强的移动宽带业务(enhanced mobile broadband,eMBB),海量机器类型连接业务(massive machine type communication,mMTC)以及超可靠低时延业务(ultra-reliable and low latency communications,URLLC)。其中,eMBB是指在现有移动宽带业务场景的基础上,对于用户体验等性能的进一步提升,mMTC则主要针对物联网的应用场景,适用于大规模,低功耗,低成本,深度覆盖的物联网终端提供网络接入服务,而URLLC则面向对数据传输可靠性以及时延要求苛刻的业务,如车联网,工业控制等场景。三大场景中包含了多样化,差异性的服务,并非所有未来的用例都对速率,覆盖有较强的需求,因此,3GPP允许运营商通过独立网络功能集合与参数配置构建网络切片,用来服务多个以及虚拟运营商的需求,同时,3GPP要求可以根据不同的市场场景动态生成网络切片。
如图1所示,为一种可能的5G网络架构示意图。图1中,核心网中可以划分为多个网络切片实体,每个网络切片实体包含一组特定功能的网络功能(network function,NF),例如图1中网络切片1包括NF1、NF2以及NF3;网络切片2包括NF4、NF5以及NF6;网络切片3包括NF7、NF8。RAN通过切片选择与路由功能模块(slice selection and routing function,
SSRF)与各个网络切片实体连通。终端接入RAN后,通过SSRF选择到合适的网络切片实体,从而接入数据网络(data network),通过特定的NF以及参数配置提供定制化的服务,从而形成5G中端到端的网络切片架构。
本申请实施例中,终端可以是可以为无线终端,例如可以为移动电话、计算机、平板电脑、个人数码助理(英文:personal digital assistant,缩写:PDA)、移动互联网设备(英文:mobile Internet device,缩写:MID)、可穿戴设备、互联网协议(英文:Internet Protocol,缩写:IP)电话、网络打印机和电子书阅读器(英文:e-book reader)等。
本申请实施例可以应用于5G通信系统或者长期演进(long term evolution,LTE)系统等移动通信系统。如图2所示,为本申请实施例提供的一种系统架构示意图。图2中所示的系统架构包括OAM网元、CN、RAN以及终端,其中CN侧包含控制面(control plane,CP)和用户面(user plane,UP)实体。RAN侧包含切片控制器和用户面锚点,以及无线接入节点。
OAM网元:根据移动运营商的实际需要,OAM网元主要负责三大类工作:操作,管理,维护,操作主要完成日常网络和业务进行的分析,预测,规划和配置工作,维护主要是对网络以及业务的测试盒故障管理等进行的日常操作活动,CN网络切片的管理功能由OAM网元发起,负责与CN和RAN对应的控制面模块进行交互,完成端到端网络切片的管理。
CN侧的CP模块:可以是移动管理实体(mobile management entity,MME)CN移动性管理锚点,CN网络切片管理,与RAN侧切片控制器一起负责端到端网络切片的连接管理,会话管理和移动性管理等功能。
RAN侧的切片控制器:位于RAN侧的CP面模块,用于根据CN的CP模块或者OAM网元配置的网络切片信息,主要负责RAN侧协议功能管理,资源分配,拓扑管理,切片间的协调管理,RAN侧移动性管理,系统信息,寻呼,测量等功能。切片控制器可以作为独立的网元,或者作为基站或RAN侧网元内部功能模块进行部署。在云无线接入网(cloud RAN,C-RAN)架构中,各个协议层可以灵活的分割,切片控制器还可以灵活的部署在基带处理单元(baseband unit,BBU)或远端射频单元(remote radio unit,RRU),或者分布式的部署于BBU与RRU中。无线接入网可以包含中继场景,切片控制器可以灵活部署于宿主基站(donor eNB,DeNB)或者中继节点(relay node,RN)中。
